Loose connections can result in a severe decrease in
voltage which may cause damage to the wires and insulation.
• Failure to make proper connection between the inverter
and the power source will result in reverse polarity. Reverse polarity will blow the internal fuses in the inverter
and may cause permanent damage to the inverter. Damage caused by reverse polarity is not covered
under the Whistler warranty.
• Making the connection between the Positive (+)
terminals may cause a spark as a result of current flowing
to the capacitors in the inverter. This is a normal
occurrence. Due to the potential for sparking, however,
it is extremely important that both the inverter and the
12 volt battery be well removed from any possible
source of flammable fumes or gases.Failure to heed
this warning could result in fire or explosion.
6. Run a ground from the Ground Lug Terminal at the
rear of the inverter to a proper grounding point using
the shortest practical length of 18 AWG wire. Selection
of the grounding point will depend on where you are
using the inverter. The ground wire may be connected
to the chassis of your vehicle or to the grounding
system in your boat or to the earth* if you are operating
the inverter in a remote location. Before connecting
the ground, make certain that the inverter is turned off.
Operating the inverter without properly
grounding it may result in electrical shock.
